IGF1-LR3 (Insulin-like Growth Factor 1 Long R3) is a modified version of the naturally occurring hormone insulin-like growth factor 1 (IGF-1). It is designed to have an extended half-life and increased potency compared to native IGF-1. IGF1-LR3 is believed to have several potential benefits for muscle gain:

  • Increased Protein Synthesis: IGF1-LR3 is thought to enhance protein synthesis, leading to increased muscle protein production. This can contribute to muscle growth, repair, and recovery.
  • Enhanced Muscle Hypertrophy: IGF1-LR3 may promote muscle hypertrophy (increase in muscle size) by increasing the number and size of muscle cells, stimulating muscle fiber growth, and supporting the formation of new muscle tissue.
  • Improved Recovery: It is speculated that IGF1-LR3 may accelerate the recovery process by promoting tissue repair and reducing muscle damage, thereby allowing for faster muscle regeneration between workouts.
